If you don't have a sharp knife, your blade requires more force in order to cut through whatever you're trying to slice. When you have to force it, there's always the chance of cutting yourself in the process.
That's why you should use this cool trick every time you get the chance!
Of course, this doesn't replace a real honing steel or a high-quality stone, but it is definitely a good backup, just in case you've left those things behind. If you're worried about damaging your window, don't be.
Glass is one of the hardest man-made substances out there and we guarantee it's much tougher than the edge of your knife.
That said, you should still be careful and maybe wear some leather gloves if you have them because accidents happen and pulling chunks of safety glass out of your hand really, really sucks.
Brian J. Hastings, this is pretty cool

although you can use glass and porcelain to Help sharpen your blade, it will not bring it to a decent point. (if the blade had large dull spots(ive tried after really dulling a knives edge on purpose. to mimic a few years of hard and verry careless use)) they should be used in the place of a strop.
and theres alwayse rocks on the ground that you can use, you just have to find the right ones (by touch) to use.
Rocks by touch?
porous stones will be better at giveing you an edge shape and smoother stones will help sharpen the edge. honing stones are porous and the glass is smooth. same concept
Ive seen this one Mason Davidson
I’ve tried this a few times. Never worked that great. It’s only to keep an fine edge that had little wear.
My dad showed me that trick when i was a kid i use it at work to touch up my buck 110 occasionally
I’ve worked in kitchens my entire career and I use my personal knives, so knife maintenance is a big deal to me. You would be surprised what you can use to hone in an edge. I often use the rounded edge of steel prep tables to bring an edge back to a nice point. Aluminum foil folded over a few times can really polish an edge nicely. Also, I’d highly recommend investing in a set of diamond impregnated sharpening cards- I use them all the time on Cozzinis. I’ve had the same $30 set for years and I use it about every other day.
That’s cool.

I’ve tried that… didn’t notice much of an improvement… and now I don’t even have a vehicle, so the “something everyone already has…” is bunk.
Aaron Lerma wow!
Bottom of a ceramic coffee cup does too
Love it
Yep sure enough
My ceramic coffee mug works great as well though it’s a bit unnerving for my clients lol.
He’s not sharpening it. Running it on the glass is the same as using running a knife on a steel. It’s just straightening the little teeth that occur when doing an actual sharpening.
